Transitional hydrogen bonds in aqueous perchlorate solution

10-Feb-2016 | Krzysztof Nieszporek; Przemysław Podkościelny; Jolanta Nieszporek, Physical Chemistry Chemical Physics, 2016

Different mechanisms of H-bond formation between perchlorate anions and water are presented using the molecular dynamics simulations. The detailed methods in searching for multi-centered hydrogen bonds are proposed. The time evolution of H-bond geometric parameters for classical, bifurcated and ...

A Dendrimer‐Based Electropolymerized Microporous Film: Multifunctional, Reversible, and Highly Sensitive Fluorescent Probe

05-Feb-2016 | Hongwei Ma, Feng Li, Peng Li, Hailong Wang, Ming Zhang, Guang Zhang, Martin Baumgarten, Klaus Müllen, Advanced Functional Materials, 2016

A dendrimer PYTPAG2 composed of a central pyrene “core” and four exterior “arms” capped with electroactive triphenylamine is developed as an electroactive precursor to prepare fluorescent films through electropolymerization (EP). The fluorescence emission comes from the central pyrene “core” and ...

Influence of Solution Composition on the Formation of Surface Nanodroplets by Solvent Exchange

05-Feb-2016 | Ziyang Lu; Shuhua Peng; Xuehua Zhang, Langmuir, 2016

Solvent exchange is a simple process of forming surface nanodroplets on an immersed substrate. In this process, the droplets nucleate and grow in response to transient oversaturation when a good solvent of the droplet liquid is displaced by a poor solvent. Here we will show how the final droplet ...

Insights into the Mechanistic Role of Diphenylphosphine Selenide, Diphenylphosphine, and Primary Amines in the Formation of CdSe Monomers

05-Feb-2016 | Ting Qi; Hua-Qing Yang; Dennis M. Whitfield; Kui Yu; Chang-Wei Hu, Journal of Physical Chemistry A, 2016

The formation mechanism of CdSe monomers from the reaction of cadmium oleate (Cd(OA)2) and SePPh2H in the presence of HPPh2 and RNH2 was studied systematically at the M06//B3LYP/6-31++G(d,p),SDD level in 1-octadecene solution. Herein, SePPh2H, HPPh2, and RNH2 act as hydrogen/proton donors with a ...

Intramolecular Hydride Transfer Reactions in (Formazanate)Boron Dihydride Complexes

05-Feb-2016 | Mu-Chieh Chang; Edwin Otten, Organometallics, 2016

The solution-phase thermolysis of (formazanate)boron dihydrides (LBH2; 2) results in the formation of aminoborane compounds (4) via a series of boron-to-ligand intramolecular hydride transfer reactions. Monitoring the reactions by NMR spectroscopy allowed identification of several intermediates, ...

Small-Angle Neutron Scattering Studies on the Multilamellae Formed by Mixing Lamella-Forming Cationic Diblock Copolymers with Lipids and Their Interaction with DNA

05-Feb-2016 | Po-Wei Yang; Tsang-Lang Lin; I-Ting Liu; Yuan Hu; U-Ser Jeng; Elliot Paul Gilbert, Langmuir, 2016

We demonstrate that the lamella-forming polystyrene-block-poly(N-methyl-4-vinylpyridinium iodine) (PS-b-P4VPQ), with similar sizes of the PS and P4VPQ blocks, can be dispersed in the aqueous solutions by forming lipid/PS-b-P4VPQ multilamellae. Using small-angle neutron scattering (SANS) and ...

Comprehensive study on critical micellar concentrations of sds in acetonitrile‐water solvents

04-Feb-2016 | Jana Šteflová, Martin Štefl, Sarah Walz, Michael Knop, Oliver Trapp, ELECTROPHORESIS, 2016

The critical micellar concentration (CMC) is one of the fundamental characteristics of surfactants and its determination is crucial for detail understanding of micelles formation. In this study the critical micellar concentration of sodium dodecyl sulfate (SDS) in presence of acetonitrile was ...

Synthesis and Characterization of [(OH)TeNb5O18]6– in Water Solution, Comparison with [Nb6O19]8–

04-Feb-2016 | Pavel A. Abramov; Tatiana P. Zemerova; Nikolay K. Moroz; Nikolay B. Kompankov; Artem A. Zhdanov; Alfiya R. Tsygankov ..., Inorganic Chemistry, 2016

Reaction of [Nb6O19]8– with H6TeO6 in water gives telluropentaniobate [(OH)TeNb5O18]6– (1) as single product, which was isolated as Na+ and mixed Na+/K+ salts. Crystal structures were determined for Na6[(OH)TeNb5O18]·15H2O (Na6-1) and K6Na[Nb5.5{Te(OH)}0.5O18.5]·26H2O (K6Na-1). Formation of 1 was ...

Suppression of Photoanodic Surface Oxidation of n-Type 6H-SiC Electrodes in Aqueous Electrolytes

04-Feb-2016 | Matthias Sachsenhauser; Karl Walczak; Paul A. Hampel; Martin Stutzmann; Ian D. Sharp; Jose A. Garrido, Langmuir, 2016

The photoelectrochemical characterization of silicon carbide (SiC) electrodes is important for enabling a wide range of potential applications for this semiconductor. However, photocorrosion of the SiC surface remains a key challenge, because this process considerably hinders the deployment of ...
